I added the zwave binding:
sudo apt-get install openhab-addon-binding-zwave
For the Aeon Labs Z-Stick Series 2 which appears as /dev/ttyUSB0 I had to add the openhab user to the dialout group:
sudo adduser openhab dialout
To bind devices I used Habmin – https://github.com/cdjackson/HABmin. I chose the complied release version – https://github.com/cdjackson/HABmin/releases. The alternative is to install source from the git and compile.
So far I have linked a RadioThermostat CT-80 with Z-wave interface and a Aoetec Home Energy Meter(2nd edition).
For the HEM it was necessary to set the mode properly for periodic updates.
The RadioThermostat only sends changes and only works in “dumb” mode when using zwave. I have not yet been able to read the humidity from the thermostat. The definition in the openhab zwave binding is imcomplete.
Radio Thermostat WiFi Module : http://ndgeek.com/ct-50/RTCOAWiFIAPIV1_3.pdf. The radio module I had was very unreliable and disconnected frequently. I did find some interesting discussions on using the WiFi module with Openhab – https://community.openhab.org/t/binding-radio-thermostat/5480 & https://community.openhab.org/t/how-to-return-current-temp-from-my-thermostat/3141

The Openhab wiki does have some good examples for the zwave interface – https://community.openhab.org/t/collection-of-working-z-wave-configs/1407
